Holo-krome 64072 Button Socket Cap Screw 3/8-16 1 in

Product Description

The HOLO-KROME 64072 is a 3/8-16 button socket cap screw designed for applications requiring a low-profile head with high clamping strength. Manufactured from alloy steel with a black oxide finish, this fastener delivers corrosion resistance and a clean appearance in finished assemblies. The hex socket drive accepts a 7/32 inch hex key for installation in tight spaces where a standard hex head wrench cannot reach. Fully threaded along its 1 inch length under head, the 64072 conforms to ANSI/ASME B18.3 and ASTM F835 standards and carries a 3A thread fit class to UNRC specification. Hardness is rated at 38 HRC, making it suitable for structural and mechanical fastening in demanding environments.

This button socket cap screw is commonly used in machine assembly, industrial equipment, jigs and fixtures, and structural panels where a flush or near-flush fastener profile is required. The low-profile button head reduces snagging hazards in moving assemblies and finished enclosures. The black oxide finish makes this screw a standard choice in applications where light corrosion resistance and a matte appearance are specified. Installation is performed by licensed mechanics, millwrights, and field technicians using a 7/32 inch hex key or Allen driver.

Installation Notes

Install and remove using a 7/32 inch hex key or Allen-drive bit. De-energize or lock out any equipment before fastener service in accordance with applicable OSHA lockout/tagout procedures. Do not exceed the torque capacity appropriate for the thread size and alloy steel grade. Inspect threads and mating tapped holes for damage or debris before installation.
